Abstract

Patients treated for prostate cancer from 1975-1982 were reviewed to assess if pre-irradiation transurethral resection of the prostate (TURP) predisposed to the formation of post treatment urethral strictures or bladder neck contractures. A total of 368 patients were treated with external beam irradiation delivered by a linear accelerator or 125I interstitial implants. Of the 253 patients treated by external beam, 138 patients had a history of at least one TURP before treatment. Implants were performed in 115 patients and 57 had a history of TURP before treatment. A total of 40 patients from both groups developed post treatment complications of urethral strictures or bladder neck contractures. Three patients developed both complications. An analysis of the 40 patients revealed that 29 (72.5%) patients had a TURP performed within a median time of 33 days prior to their initiation of radiation therapy. Of 195 patients in the prior TURP group, 29 (15%) developed one or both complications. Only 11 (6%) of the 173 patients in the non-TURP group developed one or both complications. This comparison was statistically significant with a p value of .025. Various factors analyzed including the treatment regimen, histologic grade, stage of...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
